Definitions
- the present invention relates to a cosmetic composition
- a cosmetic composition comprising an aqueous solution and a powder portion; the present invention further relates to said powder portion, to methods of preparation thereof and to its use in said cosmetic composition.
- Such cosmetic products can be produced in a wide range of colors according to the user's needs.
- dyes are usually used which are soluble and/or insoluble in the medium but dispersible therein, such as pigments and lakes.
- Pigments mainly consist of inorganic salts or oxides and such materials can be optically transparent (white pigments) or with absorption of a part of the visible spectrum (colored pigments).
- a particular category are pearly reflections pigments in which, depending on the composition, the light can be absorbed or not by a colored component (e.g. iron oxides) and can be reflected in all or some spectral components due to a thin-film interference from a transparent oxide deposited on an inert sheet (e.g. mica).
- a colored component e.g. iron oxides
- Such pigments are generally used in decorative products for the face and the area around the eyes (powder and eye shadows) and in other powder preparations.
- Lakes typically consist of water-soluble salts of organic dyes precipitated on inorganic supports (e.g. alumina, barium sulfate, etc.); such salts formed by a precipitation reaction are often used in cosmetics.
- inorganic supports e.g. alumina, barium sulfate, etc.
- lakes typically offer a brighter and more intense color compared to inorganic pigments and a fair stability and for this they are widely used in cosmetics.
- solubility of organic lakes which in any case is not null at room temperature and neutral pH, increases in the presence of high temperatures and/or basic or acid pH and/or in the presence of other solutes (e.g. salts dissociated in water, such as NaCl), causing the staining of the aqueous phase, with the generation of a solution of the dye compound dissociated in water.
- solutes e.g. salts dissociated in water, such as NaCl
- Such an effect can cause an unsightly skin staining due to the absorption of the dye into the epidermis when the cosmetic containing the lake is applied, making it difficult to remove it, if not mechanically, and with aggressive and irritating solvents.
- EP 1226811A1 refers to a solid light and mouldable cosmetic product in particular for make-up.
- the cosmetic product is subjected to an aqueous dispersion and drying processes to obtain the cosmetic powders.
- US 6143280A discloses a method of adhering dye to a silica.
- the method comprises providing a silica slurry, which includes a plurality of silica particles, depositing alum in the pores of the silica particles, reacting a base with the alum to convert the alum into aluminum hydroxide resulting in treated silica particles.
- the main difficulty to devise the solution proposed herein therefore is to find a raw material already usable in the cosmetic field but with more features, and "change" the use thereof to make it fit for the purpose.
- phyllosilicates, or layered silicates are known in the art as rheology modifiers or as thickening agents, i.e. which are able to impart a semi-solid gel structure to oils or water by modifying the rheological behavior, for example by increasing the viscosity of emulsions and thereby facilitating the application thereof. Based on the amount of rheology modifier added to the liquid, the final product will be more or less consistent.
- a powder composition consisting of one powder portion serving as a substrate (e.g. natural or synthetic talc or mica sheets) on which a powder portion layer is evenly applied with good adhesion, able to selectively capture and immobilize the organic dye when this is present in aqueous environment.
- a cosmetic composition comprising an aqueous solution and a powder portion comprising a dye, where such a powder portion is able to selectively capture and immobilize the dye released when said powder portion comes into contact with an aqueous solution, thus preventing the color migration.
- It is a sixth object of the present invention to obtain a cosmetic composition comprising an aqueous solution and a powder portion comprising a dye, where such a powder portion, before coming into contact with said aqueous solution of the cosmetic composition, has already been in contact with an aqueous solution so as to selectively capture and immobilize the dye released from said powder portion, thus preventing the color migration.
- the present invention relates to a colored powder cosmetic composition as defined in claim 1.
- a colored powder cosmetic composition comprising at least one natural or synthetic silicate and at least one dye, where said at least one silicate is able to absorb the water-soluble portion of said dye released from the dye itself when it is in contact with an aqueous solution, is able to prevent the above migration phenomenon.
- silicate means the class of (natural or synthetic) inorganic compounds mainly consisting of silicon and oxygen and based on anionic tetrahedral units of the [SiO 4 ] 4- type organized according to variable architectures and the charge of which is neutralized by metal cations.
- Such tetrahedral units can remain isolated (as in the so-called nesosilicate) or, by sharing oxygen atoms, connect to form structures of various types, as in soro-, cyclo-, ino-, phyllo- or tecto-silicates: the substitution of (tetravalent) silicon atoms with (trivalent) aluminum atoms allows the entry of positive ions in the framework, such as, e.g., in tectosilicates.
- the phyllosilicate also called layered silicate
- the phyllosilicates have a lamellar or scaly appearance, with well-defined flaking.
- the phyllosilicates are based on indefinitely flanking extended chains of tetrahedrons [SiO 4 ] 4- , joined together, on the same plane, to form layers which are repeated regularly along the direction perpendicular to the plane itself.
- Phyllosilicates may be of natural origin, i.e. extracted from rocks present in natural environments, or they may be obtained through chemical synthesis starting from inorganic precursors (sol-gel or hydrothermal synthesis).
- Such phyllosilicates can be further modified by including organic compounds within the structure which give them an oleophilic character.
- Said at least one natural or synthetic phyllosilicate is a sepiolite, hectorite, montmorillonite, bentonite-based phyllosilicate or mixtures thereof.
- the phyllosilicate comprises a quaternary salt of sepiolite, hectorite, montmorillonite, bentonite or mixtures thereof.
- Suitable quaternary salts may be, for example, ammonium, disteardimonium, stearalkonium, phosphonium, arsonium, benzalkonium, cetrimonium, pyridinium, tiazonium salts and the like.
- said at least one natural or synthetic phyllosilicate is a phyllosilicate which comprises stearalkonium bentonite and/or hectorite.
- modified phyllosilicate oleophils useful for the present invention are benzalkonium montmorillonite (available from Southern Clay Products under the trade name Garamite R 7305 (mixture)), quaternium-90 montmorillonite (available from Southern Clay Products under the trade name Garamite R 7303 (mixture)), disteardimonium hectorite (available from Element Specialities under the trade name Bentone R 38 V), stearalkonium hectorite (available from Element Specialities under the trade name Bentone R V 27), benzalkonium sepiolite (available from Southern Clay Products under the trade name Garamite R 7305 (mixture)), quaternio-90 sepiolite (available from Southern Clay Products under the trade name Garamite R 7303 (mixture)), stearalkonium bentonite (available from Southern Clay Products under the trade names of Claytone AF, Garamite R VT, Tixogel R LG, Tixogel R LG-
- the term "dye” shall mean any ingredient capable of imparting color to the formulation.
- Dyes can be distinguished in pure dyes soluble in water (water-soluble) and insoluble in water.
- Water-soluble dyes are mainly soluble salts of organic dyes or organic dyes with polar groups.
- Water-insoluble dyes are referred to as pigments; pigments are further subdivided into inorganic pigments (e.g. iron oxides, titanium dioxide, dichromium trioxide, ferric ferrocyanide, etc.) and organic pigments (water insoluble salts of organic chromophores).
- inorganic pigments e.g. iron oxides, titanium dioxide, dichromium trioxide, ferric ferrocyanide, etc.
- organic pigments water insoluble salts of organic chromophores
- Particular types of organic pigments useful for the present invention are lakes, constituted starting from said pure water-soluble dyes precipitated as insoluble salts on insoluble inorganic substrates, such as for example on talc, aluminum hydrate, calcium carbonate, sulphate barium substrates, and the like.
- Such lakes when such substrates are precipitated on such insoluble inorganic substrates, form insoluble products with pigmentary properties, that is, they color by "contact” dispersing in the application medium.
- lakes possess a better resistance to light and their coloring strength depends on the degree of fineness of the particles: the higher the degree of grinding, the higher the coloring strength and the smaller the amount of product to use.
- pigments useful for the present invention are the so-called “beads”, which are pearlescent pigments consisting of crystals in the form of thin flakes, with high refractive index, particularly used in decorative cosmetics.
- Such pearlescent pigments have a core of mica, or aluminum and potassium silicate, on which titanium dioxide and optionally metal oxides are layered/deposited. Varying the titanium dioxide thickness gives beads of different grain size and more or less colored and opaque reflections.
- Examples of pure water-soluble dyes particularly useful for the purposes of the present invention are those selected from the group comprising Yellow 5 ( CAS # 1934-21-0 ), Yellow 6 ( CAS # 2783-94-0 ), Yellow 7 ( CAS # 2321-07-5 ), Yellow 8 ( CAS # 518-47-8 ), Yellow 10 ( CAS # 8004-92-0 ), Orange 4 ( CAS # 633-96-5 ), Red 4 ( CAS # 4548-53-2 ), Red 22 ( CAS # 17372-87-1 , 548-26-5), Red 28 ( CAS # 18472-87-2 ), Red 33 ( CAS # 3567-66-6 ), Red 36 ( CAS # 2814-77-9 ), Red 40 ( CAS # 25956-17-6 ), Cochineal ( CAS # 1343-78-8 ), Blue 1 ( CAS # 3844-45-9 ), Ext.

- at least one dye preferably in an amount from 10% to 50% by weight, more preferably from 15% to 45% by weight, even more preferably from 20% to 40% by weight and most preferably from 25% to 35% by weight.
- said powder cosmetic composition further comprises at least one portion of cosmetic excipient, selected from the group comprising, for example, sericite (which is a silicate of aluminum and potassium, also called natural mica), fluorophlogopite (also called synthetic mica), borosilicate, talc, boron nitride, silica, alumina, etc. More preferably, said cosmetic excipient is natural mica or synthetic mica.
- said colored powder cosmetic composition according to the first aspect of the present invention may be used in any anhydrous product used in cosmetics, such as in a powder, face powder, blusher, pencil and the like.
- said colored powder cosmetic composition is obtained by the dry mixing of an insoluble dye with an either natural or synthetic phyllosilicate.
- said colored powder cosmetic composition was obtained by dry mixing the ingredients, i.e. without the use of aqueous solutions. Therefore, when said colored powder cosmetic composition is contact with an aqueous solution for the first time, the phyllosilicate contained in such a colored powder cosmetic composition will prevent the migration of the water-soluble portion of the dye contained in the powder.
- said natural or synthetic phyllosilicate is a phyllosilicate comprising stearalkonium bentonite and/or hectorite; preferably, said dye is a lake.
- said natural or synthetic phyllosilicate is in an amount from 50% to 90% by weight, even more preferably from 50% to 85% by weight and most preferably from 60% to 85% by weight; preferably, said dye (lake) is in an amount from 10% to 50% by weight, even more preferably from 15% to 50% by weight and most preferably from 15% to 40% by weight.
- Said colored powder cosmetic composition obtained according to said first embodiment is particularly useful for the preparation of cosmetic compositions such as cosmetic powders of the blusher, foundation, powder type.
- said colored powder cosmetic composition of the present invention is obtained by: a) first dissolving said dye in an aqueous solution, such as for example in distilled water, and adding to such a solution so obtained said natural or synthetic phyllosilicate, so as to obtain a liquid colored dispersion of phyllosilicate and dye; and, then, b) filtering said liquid dispersion of a phyllosilicate and dye and leaving it to dry to obtain a powder with low residual water, such as for example ⁇ 1%.
- said colored powder cosmetic composition is obtained, first, by contacting said dye with an aqueous solution, thus giving the possibility that as a result of such a contact, the above-mentioned problem of migration of the water-soluble portion of the dye could occur, but in fact preventing the occurrence thereof thanks to the presence of said natural or synthetic phyllosilicate, which is capable of absorbing said water-soluble dye portion and, then, drying and filtering said liquid dispersion of phyllosilicate and the water-soluble dye portion, obtaining again a colored powder.
- Such colored powder thus obtained again is more effective than the same colored powder obtained according to the first embodiment of the powder described above (which had not been subjected to a first contact with an aqueous solution and subsequent drying) since, the dye having already been subjected to migration in the step of preparation of the powder, its water-soluble portion will not tend to migrate anymore when placed in contact for a second time with an aqueous solution.
- said a natural or synthetic phyllosilicate is a phyllosilicate comprising stearalkonium bentonite and/or hectorite; preferably, said dye is a water-soluble pure dye.

- Said colored powder cosmetic composition initially had an aqueous phase which was dried and thus is not present in its final state.
- Said colored powder cosmetic composition obtained according to said second embodiment is particularly useful for the preparation of cosmetic compositions such as eye shadows.
- said colored powder cosmetic composition is obtained by absorbing a water-soluble fraction of dye released from a lake.
- a lake initially in the form of powder mixed with a suitable amount of a natural or synthetic phyllosilicate, is wetted so as to give an aqueous dispersion of phyllosilicate and of a water-soluble fraction of dye released from the lake, such as to enable the natural or synthetic phyllosilicate to absorb such a water-soluble fraction of dye released from said lake.
- the dispersion is then filtered and dried to obtain a colored powder with low residual water, such as for example ⁇ 1%.
- the colored powder cosmetic composition is obtained by contacting a fraction of water-soluble dye (in this case released from a lake) with a phyllosilicate in water and then drying such a solution again to obtain again a colored powder which has already operated to prevent migration. Also in this case, there will thus be no further possibility of migration of the water-soluble portion of the dye (lake) contained in the colored powder cosmetic composition when this will be in contact with an aqueous solution.
- said natural or synthetic phyllosilicate is a phyllosilicate comprising stearalkonium bentonite and/or hectorite.

- Said colored powder cosmetic composition obtained according to said third embodiment is especially useful for the preparation of cosmetic compositions, such as eye shadows, cosmetic inks for the decoration of the eyelids, mascara for the decoration of the eyelashes, cosmetic fluid for the lips, and pencils and eyeliners for the decoration of the eyes.
- cosmetic compositions such as eye shadows, cosmetic inks for the decoration of the eyelids, mascara for the decoration of the eyelashes, cosmetic fluid for the lips, and pencils and eyeliners for the decoration of the eyes.
- said colored powder cosmetic composition comprises a natural or synthetic phyllosilicate, at least one dye and at least one cosmetic excipient portion.

- said at least one silicate is a phyllosilicate, preferably it comprises stearalkonium bentonite.
- a lake and a natural or synthetic phyllosilicate were taken.
- the lake was a carmine (C.I. 75470), a red pigment extracted from dried cochineal insects (scientific name Dactylopius coccus ) .
- the phyllosilicate was a stearalkonium hectorite, a creamy white powder, available from Elementis Specialties, Delden, Netherlands with the initials Bentone R 27V.
- the two ingredients were dry mixed with a powder mixer for 5 minutes.
- a colored powder was thus obtained (Powder 1) with a homogeneous distribution comprising 20% by weight of the lake and 80% by weight of the natural or synthetic phyllosilicate. It was thus possible to introduce the lake in high percentages without incurring unacceptable aesthetic defects.
- An aqueous dispersion was prepared by dissolving 0.826% by weight of the pure water-soluble dye called Blue 1 (C.I. 42090), a reddish-blue powder, in 66.116% by weight of distilled water and adding 33.058% by weight of stearalkonium hectorite to the mixture.

- a colored powder (Powder 2) was so obtained, having an even color distribution in which the phyllosilicate absorbed the water-soluble portion of the dye.
- Such a powder will not be subject to the problem of migration when placed in contact with an aqueous solution and can therefore be regarded as belonging to a new class of pigments, associable to the pigment Maya Blue).
- the natural or synthetic phyllosilicates "charged" with two different pure dyes can be dry mixed and by processing such a mixture in an aqueous environment, the inter-diffusion of the dyes will lead to the creation of an end pigment having a unique color. In this way, a higher color purity than the simple mixing of traditional pigments is ensured.
- a colored powder (Powder 3) was so obtained, having an even color distribution in which the phyllosilicate absorbed the water-soluble fraction of dye released by the non water-soluble lake in aqueous environment.
- Powder 4 was prepared in a manner similar to Powder 3, using a water-insoluble lake called Red 7 Lake (C.I. 15850), reddish in color, instead of the lake called Blue 1 Lake (C.I. 42090), in the same percentages by weight.

- the powder thus obtained after sieving was then dry mixed with the water-insoluble lake called Blue 1 Lake (C.I. 42090) by means of a powder mixer for 5 minutes, obtaining a composite having the following proportions: 3.86% by weight of such a lake, 7.720 stearalkonium hectorite and 88.42% by weight of synthetic mica.
- Powders 1 and 3 described above were evaluated by means of migration and absorption tests as described hereafter.
- Some aqueous solutions of CaCl 2 were prepared at 5% by weight; to 20 g of each of such solutions, 0.5 g of pigment Carmine (C.I. 75470) and progressive amounts (from 0 to 4 g) of Bentone R 27 V (phyllosilicate of stearalkonium hectorite), which are the two compounds used to prepare Powder 1 mentioned above, were added.
- the resulting dispersions were incubated in a stove at 80°C for 24h to induce the migration of the organic pigment. At the end, the dispersions were filtered and the mother liquors were examined. The dye concentration was determined by HPLC.
- Table 1 shows the colors of mother liquor after testing and the residual amount of chromophore in mother liquor, expressed in parts per million (PPM).
- Table 1 Test Bentone R 27 VG Pigment g Sol. 5% weight CaCl 2 /g Mother liquor color Residual amount of chromophore in mother liquor/ppm 1 0.00 Carmine 0.50 20.00 ++++ intense red 249 2 0.10 Carmine 0.50 20.00 ++++ 246 3 0.20 Carmine 0.50 20.00 ++++ 21 4 0.50 Carmine 0.50 20.00 ++++ 19 5 1.00 Carmine 0.50 20.00 ++ 5 6 2.00 Carmine 0.50 20.00 + (almost clear) ⁇ 5 7 3.00 Carmine 0.50 20.00 clear ⁇ 5 8 4.00 Carmine 0.50 20.00 clear ⁇ 5 9 0.00 Blue 1 Lake 0.50 20.00 ++++ intense blue 1104 10 0.10 Blue 1 Lake 0.50 20.00 ++++ 987 11 0.20 Blue 1 Lake 0.50 20.00 ++++ 837 12 0.50 Blue 1 Lake 0.50 20.00 ++++
- Table 1 shows that, in the absence of Bentone R 27 V (tests 1 and 9), the color of the mother liquors was intense red or intense blue, respectively, depending on whether the test concerned the carmine or blue lake.
- the amount of residual chromophore in the mother liquor of such tests 1 and 9 was significantly high (about 1000 ppm).
- the coloring of the mother liquors decreased up to become clear by using increasing amounts of Bentone R 27 V and the amount of chromophore was reduced to a few units in ppm.
- Excellent results were obtained using Bentone R 27 V in amounts starting from 1 g, both in combination with carmine (tests 5-8) and with the blue lake (tests 13-16).
- Powders 1 and 3 described above were evaluated by means of resistance tests to strong acids and bases and to mono- and divalent salts.
- Table 2 shows the colors of mother liquor after testing and the residual amount of chromophore in mother liquor, expressed in parts per million (PPM).
- Table 2 shows that the tests of the invention n. 25-28, in which the lake Blue 1 Lake was combined with the phyllosilicate Bentone R 27 V, showed clear staining of the mother liquors after treatment with acids, bases or salts, and a very low amount of residual chromophore (less than 5 ppm). Conversely, the corresponding comparison tests n. 29-32, where the same Blue 1 Lake was coated on talc rather than being mixed with the phyllosilicate, the color of the mother liquors turned deep blue and the amount of residual chromophore in the mother liquors was considerably high.
- the evaluation test of powders 1 and 3 shown in examples 2 and 3 above show that, in the presence of a phyllosilicate, an excellent effect of prevention of the migration of a dye or lake is obtained when it is in contact with an aqueous solution. Conversely, the same effect is not obtained if the dye or lake is coated on a traditional excipient, such as talc, instead of being mixed with the phyllosilicate.
- each of these points are simply the three coordinates L*, a* and b*, each variable in a range from -100 to +100, where L* expresses the clarity of a color, where the maximum value of L* coincides with the paper white, while a* and b* define the hue of a color, where the more positive is the value of a*, the redder the color, while the more negative is the value of a*, the greener the color; similarly, the more positive is the value of b*, the yellower the color, while the more negative is the value of b*, the bluer the color.
- Table 3 shows the CIElab coordinates obtained by varying the type of dye used, alone or in combination with another dye, and adjusting the percentages of dye compared with the phyllosilicate.
- Table 3 Test Water-soluble dye % dye compared to Bentone R 27 V L* a* b* Mass color 33 (inv.) Red n. 33 3.50 60.32 45.17 -6.07 Amaranth 34 (inv.) Yellow n. 5 0.625 91.69 -4.3 33.07 Yellow 35 (inv.)

- Table 3 shows that by mixing a single type of dye with the phyllosilicate, colored powders were obtained substantially of the same color as the starting dye, while mixing two types of dye, in various percentages, with the phyllosilicate, colored powders were obtained having various shades of gradations. It was therefore possible to obtain a variety of colored powders to meet the user's needs to have powders to be used in the cosmetic field with more and more varied colors.
- pigment (A) based on the absorption of the water-soluble dye Blue n. 1 (2.4% by weight) on 97.6% by weight of phyllosilicate Bentone R 27 V was compared with a pigment (B) based on the same water-soluble dye and non-absorbent excipient (talc) instead of phyllosilicate.
